FILLiTuTG-CONTROL MECHANISM FOR FILLING nnerinmsirrne rooms.

Applicationfiled September 17, 1926. serial No. 136,101.

This invention relates to filling replenishing looms whereby the filling in the shuttle transferring position, following each ,replen-.

ishing operation; During the replenishing operation the substantially exhausted filling carrier in the shuttle is ejected and the end of the lillin leading therefrom extends .to the cloth selvage'. Should the filling replenishing mechanism fail to effect a trans for of fillingto the shuttle, it may happenat times that the filling leading from the substantially exhausted filling carrier may be parted by the thread parting mechanism, notwithstanding no transfer has been ef- -fected, and under these conditions one or i The more picks will fail to lay filling in the shed. H

' It has heretofore been proposed to provide means for preventing the action of the thread parting mechanism should filling replenishment not 'be effected, and such means has sometimes been associated with the transferring mechanism, so that if the transferer fails to operate, the thread parting mechanism will be rendered inactive.

It has also been proposed heretofore to provide a yielding support to engage the un der portion of the head of a filling carrier in the hopper when in transferring position and to effect movement of such guiding support by the passage of the filling carrier from the hopper to the shuttle.

The present invention contemplates the provision of mechanism for supporting a filling carrier in' the hopper when .in transferring position and to effect movement of said .supportfrom its supporting posit-ion bymovement of the filling carrier from the hopper; Advantage is taken of this movement of the filling carrier support to cause operation ofthe thread parting mechanism,

so that should a carrier not be transferred to the shuttle on call for replenishment, the thread purter will not operate.

In the present instance of; the invention,

the hopper for the filling carrier isshown as of the rotary type wherein after each transfer of a: filling carrier to the shuttle,

means are set in actuationfor moving the ro- 'tary hopper to bring the next filling carrier 1n positlonforj transfer, but as such mechs anism for rotating the hopper-does not form apart of the present invention, any appropriate means may be employed.

The loom-frame l is ofusualconstructi on, and mounted upon thefront portion of the s5 loom isthe hopper stand 2 which may be suitably supported from the breastibeam' of the loom by a base'plate 3. Mountedrforr rotary movement on the hopper stand is the filling carrier 4 which is shown as mounted,

upon a stud 5' secured to the hopper stand.

The hopper'stand is provided With a later-i, ally, extendlng stud 6 on which is mounted I;

which on call'for replenishment of filling ment or stop 19 against which rests the filling carrier when in transferring position.

Pivotally mounted upon thehopper stand 2 at 20 is a swinging arm 21 which extends downwardly from its pivotal support and at its lower end vis provided with a guiding support 22 for the filling carriers, the front edge portion of which is inclined or bevelled,

' as at 23, sothatnpon movement of a filling carrier from the hopper on replenishment, the support 22 will be moved rearwardly to thereby swing-the sw1ng1ngarm'21 rearwvardly. The support22 for thefilling carri'er in transferring position has a rearwardly'extending tail portion 24 which underlies the filling carrier nextto be moved to trans- "ferring position, as indicated in Fig. 2, and

I the top surface 25 of the tail portion 2-4E is eccentric to the arc of movement of the rotaryhopper', with the result that should a filling carrier next to be moved to transferring POSllZlOH be displaced in the rotary hopper, the surface 25 ofthe tail 2% will act upon thehead portion of such filling carrier and move it upwardly to 1ts full supporting position in the hopper. As will be noted in Fig. 2, the junction between the inclined portion 23 and the surface 25 of the filling carrier and guiding supportloears agalnst the head of'the filling carrler when in transferring positioned; a point back of:

the path off-movement of such filling carrier as itis transferred, with the result that the inclined portion 23 will cause the arm 21 to swing rearwardly as the filling carrier is transferred. e l 7 It is important that the guiding support for the filling carrier in transferring position may befproperly related to such filling carrier, and as the head portions of the filling carriers may sometimes vary in size or in accordancewith the character of the filling 1 carrier employed, means are herein provided ,ing support for the filling carrier.

for adjusting the operative position of the swinging arm 21 and consequently the guid- The swinging arm 21 is normally under the influence of a spring 26, one end of which is connected to the swinging arm at 27 and the otherend to a p1n28 extend ng fromthe hopper stand, and pro ecting from the hopper stand is a lug carrying an adjustable v stop. The adjustable stop may be variously contrived, but: in the present-instance. it 1s shown as an adjusting screw 30 which 1s threaded into the lug 29 and provided with a locking nut 31, the result being that the swinging arm and perforce the guiding support for the filling carriers may be ac curately placed inoperative position to conform to "the varying characters of the filling carriers employed. H I In accordance with one feature of the present invention, the filling carrier guiding sup-- port is associated with means independent thereof for causing the thread parting mechanism to part the thread of the outgoing filling carriers only when thefilling carrier support fliltlSWlDglIlg arm '21 are moved rearwardly by the passage of a filling carrier from the hopper to the shuttle.

This independent train of mechanism may be variously contrived, but in the present instance consists ofa stud orsupport 32 en tending from the hopper stand, and mounted for rocking movement on the stud '32 is the rocker 33, the upwardly extending arm 3&9 or which is under the influence of a pull spring 35 connected to the swingingarm 21, the result being that on rearward movement of the swinging arm due to the passage of a filling carrier from the hopper to the shuttle, the rocher'33 will be actuated;

The pull spring 35 may be varied in construction andco-nnection with regard to the swinging arm 21, but in the present instance the end portions of the spring 35 are connected to lugs '36 and 37, the former of which 7 is mounted on a pin38 extending from the arm 34 of the rocker, and the lug 37 is connected ton. pin 0.1 eateiiding fromthe arm 40 ad ustably connected to the lower end portion of the swinging arm 21, as'indicated at l1, the construction being such that should the swinging arm be moved rearwardly by the passage of a filling carrier from'thehopper at transferring position, the pull spring will yieldingly act upon the rocker 33 and, cause rocking movement thereof, and

on the return of ti e swinging arm to normal position again, the compression of the spring will move the rocker to its initial position.v

The shuttle fe-eler 15 is provided with thread parter which is best shown in detail in F 1g. l, and 1f des1red,'the thread parter may be associated with a thread clamp, as

usual in shuttlefeeler thread par clampsi i r The thread partor comprises the movable parting member or cutter 42 which is pivot:-

able thread parteris the fined thread parterr V;

14, so that upon actuation of the movable thread parter, the filling thread a which will then be in position, indicated in Fig. 4;, will be parted or cut. If desired, the thread pater mayhave'associated therewith the: thread clamping members 45' and 46,v but as such parts are not essential to the 'invenwell-known inthe art.

tion they may be of usualconstruction now 1 Themovable parting member 42 is pro vided with an uppercam surface 47- which .is engaged by a parter actuator 48 having an en'd'portion 4C9 overlying the cam surface i7. The parter actuator 48 is secured to the rocker 33 at 50, and inthe presentinstance of the invention is shown as secured to the rocker by means of a screw bolt 51, so that the actuator may be adjustable with respect to the rocker to properlyact upon the partingmeinber of the thread parter.

From the construction described it will be obvious that on call for replenishment of filling, the transferrer will move the filling carrier then in transferring position from the hopper to the shuttle, and during such movement the guiding support 22 and the swinging arm 21 will be moved rearwardly. Simultaneously with the call for replenishment of filling, the shuttle feeler 15 is moved rearwardiy to shuttle, feeling position, the,

guiding support 22 and swinging arm 21 are moved rearwardly as described during replenishment, and the rocker 33 will be yieldingly rocked under the action of the spring connection to move the thread parting actuator eddownwardly and cause the one 4-9 thereof to act upon the cam surface 47 of the parter to thereby part the thread leading to the outgoing filling carrier.

Where a thread clamp is employed in connection with the parter, it is usual to maintain the end of the filling leading to' the cloth selvage under control of the clamp, a condition which is indicated in Fig. 1, and on rearward movement of the feeler, means are provided to open the thread parter and clamp, such means being av trip 51 mounted upon an arm 52, as usual, and acting upon :i-pin 53 extending from the thread parter and clamp. After replenishment has been effected and the outgoing filling thread parted, the hopper will be moved to bring the nee; filling carrier in position for transfer, and during suchmovement the surface of the filling carrier guiding support 22 will bear upon the head of the filling car -ier asit moves to transferring position and force into its proper operative position in the hopper.
